Specification of Letters Patent.

Application filed March 3D, 1908. Serial No. d24,196.

My invention relates to improvements in water tank heaters and feed cookers for the class of tanks used to water cattle, sheep etc. on large farms, ranches or other places where stock is kept.

The object of the invention is to provide anew and improved device of said class, which is simple and durable, easily operated and of a minimum cost to construct.

In the drawingsFigure 1 is a top view of the complete device and a portion of a circular tank in which the device is applied. Fig. 2 is a front view of the device with the furnace door removed and the outline of the tub in dotted lines. Fig. 3 is a left hand side elevation of the complete device in place in a tank, with the latter in section.

Fig. 5 is a horizontal section of Fig. 4 on the line aa. Fig. 6 is a top view of the grate. rear end elevation with the end wall removed and some minor parts omitted. Fig. 8 is a partly sectional elevation of the main body of the device with a portion of one side wall removed as on the line 17-12 in Figsy2 and 7. Fig. 9.is a detail view of the damper used to regulate the course of the draft. Fig. 10 is therear end plate of the heater seen from its Referring to the drawing by reference numerals, 1 and 2 represent respectively the .body and bottom of any water tank used to water stock, and 3 designates the water in A such tank.

The heater proper is composed of a water tight almost cylindrical shell 8, supported on legs 9, securedby bolts 10 to the bottom of the tank, and 'a fire flue or fire box 5 held concentrically therein by having one end inserted in the groove 8 (see Fig. 8) of the rear 1 plate 6 of the shell and its front portion riveted to a flange 7 (see Fig. 2) of the annular front end plate 7 of the shell.

The fire boX- 5 is projected forward, passed through a hole 4 in the side of the tank, in

which it is fitted or made water tight, and outside the tank is se ured on it a casting Fig. 4 is a 'front' Fig. 7 is a a latch 43 engaging a catch 45 on the casting. Said door is of the type shown in Figs. 4 and 5 to have a draft regulating plate 48 pivoted at 49 and provided with apertures 47 through which and a similar aperture 46 in the door,

more or less air is admitted to the fire (not shown) resting upon the grate 13, which is supported by bars and brackets 16 in the fire box. To prevent sparks from flying out through the openings 46-47, and to prevent over-heating of the door, the latter carries on suitable studs or brackets 50 some distance from the inner side of the door a shielding plate 50, which may have apertures 51, only they must not register with the apertures 4647. The air thus passes to the fire partly through the apertures 51 andpartly over the edges of the shield, the latter being smaller than the door opening.

From one side of the shell 8 and communicating with the interior thereof extends upwardly a smoke flue or chimney terminate ing in a smoke stack 22 having a spark ar-- rester 23. Into this flue 20 the hot air and smoke from the fire may pass either directly through apertures (see Fig. 8) in the side of the fire box nearest the flue, .or a damper 31 operated by a rod may close said a er tures and the hot air and smoke must t en ass out through the port 18 in the top of the firebox and heat the-entire shell by passing as arrows d, e, f into the smoke flue 20. Said flue 20 is provided with a horizontal branch 24 supported. at 24 upon the edge of the tank and terminating in a smoke stack 22* with spark-arrester 23". The upper side of the horizontal branch flue 24 is formed into or with a pan 29 in which to heat or cook feed for pigs and such other stock as may sometimes need it.

At the junction of the fines 20 and 24 is pivotally arranged a damper 25 operated by a rocker arm 26 held by a weight 28. This damper may close alternately the passage of the smoke from either the vertical or the horizontal flue. When the feed box or pan 29 is to be heated the dam er is swung across ing a fire on the grate and then closed so as 'to cause the hot air to heat the shell 8 and its If however the feed pan is tobe heated in a 40 to which is hinged at 42 a door 41, having hurry or'to a high degree, then the damper 31 1 10 may be opened so as to let the hot air ass to the flue 24 without paying out any its x supports it by heat through the shell'8: I

The dampers may be arran ed and operated in various manners, but erate the damper 31 by a vertical rod 35, which projects upwardly through one-of the shoulders 21 of the flue and is provided with a side projection 37 supported ona-pivw oted latch or catch 36 when the damper-fie closed, and when it is to be open, as at 31 the latch 36 is disengaged from the rod and the latteris allowed to dro until the damper resting t e position 31- in the flue 20.

In Fig. 9 is shown that the u per damper .25 has a clearing notch 38 for t he rod of the lower dam en The back Wa 6 of the heater may be r0- vided near the-bottom with a hand hole ate 60 (see Fig. 10), which may be remove and thereby make easy access-to clean cinders,

ashes and'dirt that may have fallen between the fire-box and the shell 8.

Having thus. described my invention, what I claim is:

1. In a device of the kind described the combination with a water tank, of a heater having le s fixed upon the'bottom of the lindricalshell submerged in the water in the tank some distance from its walls and having atjione side'an opening with a vertical smoke flue extending above the water and terminating ma smoke stack with a spark arrester on it, a cylindrical fire box with a rate therein, said fire box bein substantia y concentrically mounted int e shell and extending throughout its entire length, it also extending beyond the front end of the shell and W317 ter tight tbrou hthe side of the tank, a fire door with suita le frame mounted on the end of the fire box that protrudes beyond the wall ot the tank, said fire box having near its top an opening for the hot air and smoke to escape'into and pass throu h the entire shell to the smoke flue, and anot er opening'directly prefer to op:

tank; sai heater comprising a horizontal 'cy-' tical and the horizontal flues for directing the ibotair and smoke alternately into either of them as. may be desired.

2. In a device of the kind described, the combination with a water tank, of aheater having legs fixed upon the bottom ofthe tank; said heater comprising a horizontal cylindrical shell submergedin the water in the.

tank some distance from its walls, and having at one side a longitudinalopening, a flat broad smoke .flue'extendin from said 0 ening verticall up through t e water an being above t e water reduced to a smokestack, a horizontally flatbroad branch flue extending from one side of the vertical line and being su ported on the tank and having its outer en reduced to an u right smokestack; a damper arranged at t e junction .of

the vertical and the horizontal flat fluesfor directing the hot air and smoke alternately into either of them, a feed-cookin pan formed in the up er side of the horizonta flue; a fireboxin e shell and extending beyond one end of it and water tight through one side of the water tank a damper arranged to directthe hot air and smoke from the fire alternately into the smokestack directly from the fire, or indirectl around the firebox so as to heat the entire s ell; said dam er having a controlling .rod extended upwar y throu h the vertical flue and provided with a ham le near the s'mokestack on said-flue.

In testimony whereof I afiix my signature, in presence of two witnesses.
